Big single or double room

Well, hello there :)

I'm a 22 years old guy,

I'm a professional, working in Harrods.

What I'm looking for?

I'm looking for a big single or a double room in a property, which is in a walking distance to the tube.

Basic furniture like a bed, desk, night stand chair and a wardrobe. (box room is not suitable).

Where? - Walthamstow, Leyton, Leytonstone, Stratford.

Dishwasher preferable but not necessary.
